A reciprocating absorption refrigeration system without a circulation pump
By using a reciprocating absorption refrigeration system without a circulating pump, two generators and absorbers are alternately supplied with cooling water and heat source. Combined with a condenser and evaporator, this solves the problem of high energy consumption of circulating pumps in traditional systems and achieves a refrigeration effect with low energy consumption and high compactness.

AI Technical Summary
Technical Problem
Traditional absorption refrigeration systems require the use of circulating pumps to transport the solution, resulting in high system energy consumption, increased costs, and poor compactness.
Method used
The reciprocating absorption refrigeration system without a circulating pump uses two generators to alternately supply cooling water and a heat source. Combined with a condenser and an evaporator, a spray pump is used to achieve the reciprocating circulation of the solution, thus avoiding dependence on a circulating pump.
Benefits of technology
It reduces system energy consumption, improves compactness and reliability, and the pump's shaft power is only 14% of that of traditional systems, with a head requirement of less than 10m.

Abstract
The utility model discloses a refrigeration technical field's reciprocating absorption refrigeration system of no circulating pump, including condenser and evaporator still include first generation absorber and second generation absorber, the gaseous refrigerant import of condenser is connected the gaseous refrigerant export of first generation absorber and second generation absorber respectively through pipe valve spare, the gaseous refrigerant export of evaporator is connected the gaseous refrigerant import of first generation absorber and second generation absorber respectively through pipe valve spare, and the application makes refrigerant reciprocating generation and absorption between two sets of equipment through two generation absorbers alternately and passes in cooling water and heat source, collocates condenser and evaporator to reach refrigeration effect, and is equipped with the spray pump on the generation absorber, and the import and export of each spray pump are located in the same container, and the required lift of pump is small, solves the traditional absorption refrigeration circulating pump to need enough big lift to overcome the resistance of pumping solution from low pressure side into high pressure side.
